Firstly,aimed at the requirement of the performance of the hydraulic control system of 3150KN type four-pillars hydraulic machine,overall design of this system was proposed.Furthermore the configuration of loops,the type of main components were given.Moreover it was modeled with AMESim.By dynamic simulation of system,the problems such as excessive pressure impact and too slow return rate exist in preliminary design were found.Finaly,additional a pressure-release loop and inrease the diameter of the rod were put forward as solutions to solve those problems. Therefore,the purpose of optimizing system,shorting design cycle and improving the stability of system can be achieved. Keywords Punching machine Hydraulic presses Hydraulic control system simulation
